I got a new (android) phone a few days ago and have been slowly adding apps to it.

In case it hasn't been mentioned yet, many of the good Chinese apps are no longer in play store, which means you can either slideload the APKs yourself or use a play store clone like Yingyongbao. Both methods require enabling the "installation from external sources" permission.

The only Chinese apps I've included thus far are:
-WeChat
-Alipay
-Baidu Maps
-Ele.me
-Dianping
-Didi
-China Unicom (to manage my phone plan)
-two bank apps

I'm sitting on the fence about several others that I haven't used much recently, but could come in handy.
